REVERSIBLE WASTE-COCK.

SPECIFICATION forming part of Letters Patent No. 615,546, dated December6, 1898.

Application filed April 20,1897- Sefifll NO- 1 (N0 model-l To all whom,it may concern.-

Be it known that I, ISAAC N. GLAUBER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Reversible W'aste Cocks;and I do declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to'improvementsin reversible waste-cocks; and theobject of my invention is toprovide simple means for reversing thewaste-passage from left to right or right to left, substantially asshown and described, and more particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation, partly insection, of my improved cock and showing the water-passage open and thewaste closed; and Fig. 2 is a central vertical section on line 2 2,Fig. 1. Fig.

3 is a cross-section on line 3 3 of Fig. 1, showand reversed from theposition as shown in Figs. 3 and 4.

A represents the body of a cock, having the usual water-passage 2centrally therein and a plug B seated and held in place in the body bynut and washer 3. The plug B has a central passage 4, which provides anopen way for the water through the cock when in the position as shown inthe several views, but which, if the plug is turned a quarter-turn, willclose the water-passage 2 from one side only, and that side to be thepressure side and the opposite side the waste-water side. To provide forthe waste,I employ a passage 5 in the plug, which, if it be in line withwaterpassage 2, will open the wasteway either from the right or the leftthrough central passage 4 and a waste-opening 6 in the side of the bodyof the cock. The waste-passage 5 in the plug ison a lower plane thanwaste-opening 6 in the body, and when the water-passages 2 and 4 areopen the waste-passage 5 is closed by the sides of the seat, whether itbe to the rear, as shown in Fig. 4, or to the front, as seen in Fig. 6.-

To reverse the waste from the right or from the left, I provide the bodywith a longer neck 7 than usual, and in this neck I tap a screwhole forscrew 8, the inner end of which forms a stop to limit the rotation ofthe plug to a quarter-turn. Near the top of the plug and within the sameare provided two slots L and R, into which the end of screw 8 projects,and the shoulders at each end of the slots form stops to limit themovement of rotation of the plug to a quarter-turn.

When the screw projects into slot L, the direction of rotation of theplug serves to bring waste-passage 5 from the rear to the left, as shownin dotted lines in Fig. 4, and in this case the waste is from the leftand the pressure from the right. When the screw projects into slot R,the direction of rotation ofthe plug brings waste-passage 5 to theright, and the waste is now from the right and the pressure from theleft.

Plumbers often find that it is impossible to determine from which sidethe pressure is to come, and the object of this invention is to providea simple means to change the position of the waste-hole if it is foundthat the waste-passage does not correspond to the waste side. As seen inFigs. 1, 2, 3, and 4, the waste is from the left; but suppose that amistake had been made and it was found that the pressure was from theleft. It would be necessary to reverse the plug by giving it ahalf-turn, so that the waste-passage 5 would be in proper position to bebrought into alinement with passage 2 at the right. Fig. 6 shows thischanged position, the screw 8 having been removed from slot L to slot R;but

versible cock lie in the simple means by which it can be changed from aleft to a right or a right to a left. To make this change, it is onlynecessary to withdraw the end of screw 8 from one of the said slots,give the plug half a turn, and turn said screw into the other slot, andthe desired reversal has been effected. This can be done without evenremoving the screw 8 entirely from the neck 7 by merely unscrewingenough, so that the end will not project beyond the seat and come intocontact with the shoulders of the slots. By placing the slots in thebody of the plug and within the neck 7 all the Working parts are removedfrom sight and from liability of injury while shipping, handling, or thelike, and the check or stop of the plug is covered to preventobstructions gathering therein.

As a modification of this construction I could place the recesses in theneck 7 of the body and form an overhanging flange or projection on theplug to support the engaging screw ,8; but this is a manifest equivalentof my invention.

It will be noticed that the stop projection or screw 8 is never whollyremoved to change the cock from a right to a left or reversely, and inthis particular is believed to be first and original. All other deviceshaving reversal or changing of the plug in view, so far as I know, aretransferred from one-position or hole to another. My stop remains in thesame place in all cases, and there are no un occupied holes or othervacant places by reason of removal of the stop, as in other deviceshaving a like object in View. Again, it is wholly immaterial in thiscock where the waste-hole in the plug may be when adj ustment'of theplug is made from a right to a left or a left to a right hand plug-thatis, whether it is opposite the waste in the body or on the same sidetherewith-because by having it out of line or alinement with thewaste-hole 6 in the body there can be no leakage between s'aid holes.This is a matter of great advantage in setting the plug and, combinedwith the very simple stop mechanism shown, makes an exceptionally simpleand efficient waste-cock.

What I claim as new, and desire to secure by Letters Patent, is-- I Inwaste-cocks, the body having a waste opening and the plug having awaste-openin g out of line therewith, so that said openings cannotcommunicate directly with each other, said plug having recesses in itsneck and a screw in the body engaging one of said recesses,substantially as described.

Witness my hand to the foregoing specification this 13th day of April,1897.
